What Is a Free Tools Electric Vehicle Fuel Savings Calculator?
A Free Tools Electric Vehicle Fuel Savings Calculator is an online tool that estimates how much money you can save by driving an electric vehicle (EV) instead of a gasoline or diesel vehicle. It compares the cost of electricity used to charge an EV with the cost of fuel required for a comparable internal combustion engine (ICE) vehicle over a selected distance.
Whether you’re considering buying your first EV or already own one, this calculator helps you understand your potential savings on fuel costs over time.
How Does an Electric Vehicle Fuel Savings Calculator Work?
The calculator compares the operating costs of an electric vehicle and a gasoline or diesel vehicle using information you provide.
Typical inputs include:
- Annual driving distance (miles or kilometers)
- EV energy efficiency (miles per kWh or kWh per 100 miles)
- Electricity price ($/kWh)
- Gasoline or diesel vehicle fuel economy (MPG or L/100 km)
- Fuel price per gallon or liter
- Charging efficiency (optional)
The calculator estimates:
- EV charging cost
- Gasoline or diesel fuel cost
- Monthly fuel savings
- Annual fuel savings
- Five-year and lifetime savings (on some advanced calculators)
Information You’ll Need
1. Annual Driving Distance
Enter how far you drive each year.
Example:
- Annual Mileage: 15,000 miles
Drivers who travel more generally experience greater fuel savings from switching to an EV.
2. Electricity Rate
Enter the price you pay for electricity.
Example:
- Electricity Cost: $0.15 per kWh
You can usually find this rate on your electric utility bill.
3. EV Efficiency
Electric vehicles measure efficiency differently than gasoline vehicles.
Examples:
- 3.5 miles per kWh
- 4.0 miles per kWh
- 28 kWh per 100 miles
More efficient EVs require less electricity for the same distance.
4. Gasoline Vehicle Fuel Economy
Enter the fuel economy of the vehicle you’re comparing.
Example:
- 30 MPG
5. Fuel Price
Enter the current gasoline or diesel price.
Example:
- Gasoline Price: $3.80 per gallon
Example Calculation
Suppose you drive:
- Annual Distance: 15,000 miles
- EV Efficiency: 4 miles per kWh
- Electricity Rate: $0.15/kWh
- Gasoline Vehicle: 30 MPG
- Gasoline Price: $3.80/gallon
EV Electricity Cost
Electricity used:
15,000 ÷ 4 = 3,750 kWh
Charging cost:
3,750 × $0.15 = $562.50
Gasoline Cost
Fuel required:
15,000 ÷ 30 = 500 gallons
Fuel cost:
500 × $3.80 = $1,900
Estimated Annual Fuel Savings
$1,900 − $562.50 = $1,337.50
Formula Used
EV Energy Cost
EV Charging Cost = Electricity Used × Electricity Rate
Gasoline Cost
Fuel Cost = Fuel Used × Fuel Price
Fuel Savings
Savings = Gasoline Cost − EV Charging Cost
Benefits of an EV Fuel Savings Calculator
1. Estimate Annual Savings
See how much money you could save each year by switching to an electric vehicle.
2. Compare Different Vehicles
Compare multiple EVs with:
- Compact cars
- SUVs
- Pickup trucks
- Luxury electric vehicles
You can also compare them with different gasoline or diesel vehicles.
3. Budget Transportation Costs
Estimate:
- Weekly fuel costs
- Monthly transportation expenses
- Annual operating costs
4. Support Buying Decisions
A fuel savings estimate can help determine whether the long-term operating savings of an EV offset its purchase price.
5. Evaluate Different Electricity Rates
If your utility offers:
- Off-peak charging rates
- Time-of-use pricing
- EV charging discounts
You can compare savings under different rate plans.
Additional Savings Beyond Fuel
While this calculator focuses on energy costs, EV owners may also benefit from:
- Lower routine maintenance costs
- No oil changes
- Fewer moving engine parts
- Reduced brake wear through regenerative braking
- Potential incentives or tax credits (where available)
These factors can further reduce the overall cost of vehicle ownership.
Factors That Affect Fuel Savings
Your actual savings depend on:
- Electricity price
- Gasoline or diesel price
- Annual mileage
- Vehicle efficiency
- Charging efficiency
- Driving habits
- Weather conditions
- Terrain
Higher gasoline prices and greater annual mileage generally increase the potential savings from driving an EV.
Example Comparison
| Category | Electric Vehicle | Gasoline Vehicle |
|---|---|---|
| Annual Distance | 15,000 miles | 15,000 miles |
| Energy/Fuel Cost | About $563 | About $1,900 |
| Annual Savings | Approximately $1,338 | — |
Figures are estimates for illustration and will vary based on actual vehicle efficiency and local energy prices.
